IMPROVEMENT IN VALVES FOR TRAPS.

Specification forming part of Letters Patent No. 183, [25, dated October 10, 1876; application filed August 21, 1876.

To all whom it may concern:

Be it known that I, GEORGE BUTLER, of Southwark, in the county of Surrey, England, engineer, have invented Improvements in Valves or Cocks, of which the following is a specification The object of my invention is to so construct a ball or other valve as to cause the flow of branch, terminating in an enlarged chamber,

I), through the center of-which extends the outlet-branch c to above the level of the said inlet. At the upper endof the outlet-branch c I form a partition or diaphragm, d, which extends across between the exterior of such outlet-branch and the side of the chamber b, and is provided with one or more openings, 6. By this arrangement a sufficient area of passage is provided by the opening or openings 6 for the flow of the liquid, while at the same time the partition (1 exercises a restrictive action upon the incoming fluid, and thereby pre vents any shaking of the valve. The valve proper consists of a disk, f, of metal, provided on its under side with a sunken washer, g, of leather, india-rubber, or other suitable material, and having on its upper side a stem or projection, h, which passes through an opening formed in a cover, 2', fitted to the top of the chamber. A spindle, I, attached to the under side of the valve, passes down the interior of the outlet-branch a, and is connected at its lower end to the short arm of the lever m, carrying the ball or float n. This lever, which is by preference pivoted at n to a lug, 0, formed on the exterior of the outlet-branch c, as shown, passes through an opening, 1), in the outlet, and enters a slot in the lower end of the valvespindle I, so that the rise and fall of the ball or float n in the tank operates the valvef.

I claim as my invention The combination of the valvef, inlet a, and enlarged chamber 1), with the outlet 0 projecting through the said chamber, and with the partition 01, having an opening or openings, 0, as and for the purpose set forth.

In witness whereof I have signed my name to this specification in the presence of two subscribing witnesses.

G. BUTLER.
